Background: Treatment of tibial diaphyseal nonunions are rather difficult. Plate-screw, intramedullary nailing and external fixation are the methods used for treatment. The aim of this study is to evaluate the treatment results of aseptic diaphyseal nonunions following tibia fractures by intramedullary compressive tibia nailing (IMCN) with or without bone graft. Materials and Methods: Twenty eight patients who had aseptic tibial nonunion without bone defects operated between 2005 and 2015 were included in the study. The mean age of our patients was 36.4 years (range 20–56 years). There were 22 males and 6 females. Fifteen of the patients exhibited hypertrophic nonunion and thirteen exhibited atrophic nonunion. The average time between fracture occurrence and presentation to our department was 1.6 years (range 1–20 years). All patients underwent fibular osteotomy by removal of a 2 cm bone block from the middle one-third of the fibulas. In all cases, IMCN was applied following the reaming procedure, then maximum bone contacts were achieved manually between proximal and distal bone fragments afterward, and dynamic compressive fixation with 1 mm of compression was performed by a single rotation of the compression screw at the top of the nail. Direct X-ray images were assessed according to the Rust criteria, and functional outcomes were assessed according to the Johner–Wrush criteria. Finite-element analysis was performed for 1 mm of compression. For statistical analysis, Fisher's exact test, Pearson's Chi-square test, and Mann–Whitney U-test were used. Results: Union was achieved in all patients. Radiological union was obtained at an average of 15.5 ± 1.86 weeks. Functional results were found to be good or excellent in 25 (89.2%) patients and average or poor in 3 (10.8%) patients. One patient developed skin necrosis at the wound site, which was treated with rotational flap and skin graft. None of the patients developed implant failure, thromboembolism, deep-vein thrombosis, or infection. Conclusions: The use of compressive intramedullary nailing with or without bone graft is an effective method for the treatment of tibial nonunion.
